Abstract

An ignition device for igniting a fuel / air mixture in a combustion chamber (23) of an internal combustion engine by corona discharge, comprising an ignition electrode (9), outer conductors (1, 3) surrounding the ignition electrode (9), said outer conductor having a front end and The rear end, and comprising an electrical insulator (8) arranged between the ignition electrode (9) and the outer conductor (1, 3), from which at least one tip (10) of the ignition electrode (9) protrudes. At least one tip (10) of the ignition electrode (9) is arranged in a space (18) shielded by the insulator (8) in association with a cap (4) having an inner side facing the insulator (8) and oriented towards Remote from the outer side of the insulator (8) and one or more holes (7) through which the shielded space (18) is connected to the space arranged on the outer side of the cap (4).

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and in particular relates to a design scheme and structural features of a corona ignition device. Background technique [0002] The invention is based on an ignition device as known from DE 10 2010 045 170 B3, having the following characteristics: comprising an ignition electrode and an outer conductor surrounding the ignition electrode, said outer conductor having a front end and a rear end, and being arranged at the ignition electrode and an electrical insulator between the outer conductor and at least one tip of the ignition electrode protruding from the insulator. Ignition devices of this type are known as corona ignition devices or HF ignition devices. [0003] DE 10 2010 045 170 B3 discloses how a fuel / air mixture in a combustion chamber of an internal combustion engine can be ignited by a corona discharge generated by the internal combustion chamber. To this end, the ...
